You have no clue what a RPG is. JRPG is not RPG, it's a genre based on D&D, but with no actual D&D elements on it. The RPG part of JRPG is a loose appropriation. I cannot think of a single JRPG that has roleplay. True RPGs are Baldur's Gate, Fallout 2 and Witcher 3.
The thing is, JRPG as a genre, never really evolved. There's no random encounters and turn-based combat in some games anymore, but the rest is all the same. Atlus is the best one with SMT and Persona, but there's barely any difference between those games and what Enix did so many years ago, they're still badly written. The rest of the industry, on the other hand, evolved heavily, the difference between Planescate: Torment and The Witcher 3 is huge, even though both of those games share a lot of the same elements. JRPG is a genre fated to be niche, unless the developers take it to another level. That's why you don't like JRPGs anymore, that's a tired genre that had it's time, but it's struggling to stay alive. Or maybe you just want the old JRPGs, with less western influence, and if that's the case, there's still tons of them on the 3DS and PS Vita, pretty much the same games as before, but with new graphics.
I have to ask if your post is a joke or satrical because this is pretty out of touch. Is your post for real? I'm gonna take it as you're being serious. First of all, let's clear of up this JRPG nonsense. It only means Japanese Role Play Game. Turned based RPG doesn't mean JRPG or vice versa. Some people conflate those two together. JRPG is not a genre. It only describes RPGs that come from Japan. Turn based RPGs is a genre and that's the term you two should be using. FF VII, FF tactics, Mario RPG, Dark Souls, and Dragon's Dogma are all JRPGs.
The parts I bolded are nonsensical to the point that it makes me wonder if you ever played any JRPGs of old or new. It's like you're saying that water isn't wet or that fire isn't hot. JRPGs are RPGs. Chrono trigger or FF tactics are good examples of role playing in JRPGs.
As for your comment about JRPGs never really evolved.... I'll address this in both ways that JRPG could be used. Turn based RPGs evolved a long time ago. Over the course of decades, you can see them experimenting with the genre with different games. Changing battle mechanics and adding in more action to it for the most part. FF XII and games similar to it are the evolved form of turn based RPGs. JRPGs as a whole have evolved greatly. You can see the vast difference from FF III to Dragon's Dogma.
